LOADING AND GRADING DEVICE.

Application filed November 7, 1921.

To all whom it may concern:

Be it known that 1, JOHN R. CANIoN, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in- Loading and Grading Devices, of which the following is a specification.

This invention relates to new and useful improvements in loading and grading de vices.

The object of the'invention is to provide a loading device of a practical nature which will be rapid and efiicient in operation and which will be easy to control. A further object of the invention is to provide a device of the character described which may be readily changed into a. grader.

In carrying out the invention I provide a wheel supported frame which carries a motor for driving the same and a steering gear. A vertically adjustable screw conveyor is mounted transversely of the device, and is driven from the motor. An elevator is carried at one side of the frame and is also driven by the motor. The elevator is arranged so that it can be detached when the devicevis used as a grader. The transverse conveyor has the advantage of loosening as Well as conveying the material.

A construction designed to carry out the invention will be hereinafter described together with other features ofthe invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompany ing drawings. in which an example of the invention is shown and wherein:

Fig. 1 is a plan view of a machine constructed in accordance with my invention,

Fig. 2 is a sectional view on the line 22 of Fig. 1,

Fig. 3 is a cross sectional view on the line 3 3 of Fig. 1, v

to the ends of a transverse connecting rod 16. An arm 17 depending from a steering post 18 has suitable swinging connection with the rod so that when said post is rotated the arm will swing the rod 16, which in turn will swing the spindles and turn the front wheels. The forward end of the post is mounted in a bearing box 19 supported on the front of the frame. The post inclines upwardly and rearwardly and is supported in an arch 20 mounted between standards 21 on the rear of the frame. A hand wheel 22 is fastened on the post in front of the seat 23.

The frame has rear extensions 10 in which a rear axle 24 is mounted, said axle including an ordinary differential 25. Traction wheels 26 are secured on the ends of the axle. A platform 27 is mounted at the central portion of the frame and supports a gasoline engine 28, which includes a clutch Q9 and a transmission 30. A drive shaft 31 extends from the transmission to the differential. By means of the transmission the speed of travel of the machine may be regulated.

At each side of the central portion of the frame a pair of guide posts 32 are provided. Between each pair of posts :1 rectangular hanger member 33 is mounted to slide vertically. Each hanger member has bearing-boxes 3% at its center for receiving the ends of a conveyor shaft 35 on which a screw conveyor 36 is mounted. The hanger member at the discharge end of the conveyor is cut out zit-37 as is shown best in Fig. 5, to discharge the load. A curved scoop 38 extends from one member to the other and is suitably attachedthereto. The scoop overhangs the conveyor and has its lower edge substantially .on a level with the conveyor. From each member 33 a rack bar 39 extends upwardly thru a top side bar 40, each of which is supported at l with and are mounted on the forward ends of counter shafts 44 suitably mounted on the side bars 40. Adjusting shafts -15 are suitably mounted on the upper ends of the standards 21 and 42, and each has a bevei gear 46 on its outer end. Each gear l meshes with a bevel gear 47 on the rear end of the, ad acent counter shaft. On the ner end of each shaft 45, a hand wheel 48.

is fastened. These hand wheels are justiin front of the seat on each side thereof and 52 is mounted in a boot 53 on the outer sides shaft58 on'one end sprocket wheel .boot engage eyes v57 of which upwardly inclined supports 54 are fastened. The roller 51 is mounted between the upper ends of said supports so as to overhang and" discharge into a wagon or truck driven thereunder.

The boot is removably, fastened by means of hangers 55'which engage over the frame 10. Hooks 56 pivoted to the sides of the carried by the lower rails of the frame 10. The roller 52 has a of which is mounted a 59. This sprocket wheel supports and drives one end of an endless chain 60, which has its upper end supported on a wheel 61, the latter being, connected with and driving the roller 51. By this arrangement the elevator. belt is positively driven from both ends.

The shaft 58 is connected with a drive shaft 62- by acoupling 62'. The shaft '62 is supported in brackets 63 carried by the frame 10. When it is desired to disconnect and remove the elevator from the frame it is merely necessary to disengage the coupling 62 and remove the hooks56 from the eyes 57, after which the boot may be lifted from the frame.

The shaft 62 has a worm gear 64 fastened thereon between the brackets and this gear is driven by a worm 65 resting thereon. The worm is mounted on the end of a transverse shaft 66 mounted on the platform 27. The engine 28 has a forward clutch 67 engaging a bevel gear 68 mounted in a bearing bracket 69. The gear is disposed between and drives a bevel gear 70 fastened on the end of the shaft 66 and a bevel gear 71 mounted on the inner end of a transverse shaft 72. The shaft 72 extends beyond the side of the frame and has a sprocket wheel 73 mounted thereon. This wheel drives a wheel 75 by means of an endless chain 74. The wheel 75 is mounted on the end of the shaft 35 and revolves the latter, whereby the screw 36 is revolved.

When it is not desired to drive the screw conveyor and the elevator, the clutch 67 is disengaged from the gear 68.

. position.

As the machine is driven forwardly the scoop -38 scrapes up the dirt or gravel, as the case may be. The screw conveyor 36 conveys the material as well as cutting into the same. The material is conveyed to the end fthe scoop and discharged thru the opening 37 into the boot 53 from which it is picked up by the buckets 50, and elevated so as to be discharged from theupper end of the elevator. The scoop and conveyor may be adjusted vertically so as to raise the same when not in" use and lowered when in use.

When the machhine is to be used as a graderthe elevator is removed as has been described. A ditching blade 76 which is hinged at 77 to. the forward end of the frame at right hand side, is lowered into This blade is used to out along a bank or in a ditch. When not in use a lever 78 which is pivoted to the blade and connected with the upper end of the adjacent rack bar 39, is disconnected. The lever has a ring 79 which may be engaged with a hook ,80 on the standard 41 whereby the blade is swung upwardly. A brace 81 fastened to the frame is engaged by the blade for holding the latter in position.

Various changes and modifications may be made without departing from the spirit of the invention. 4 i
